Long before there was a HOC, I went through a Brentston-esque phase of buying and selling guitars. And I mean a lot of guitars (hence Brentston-esque). I bought a shit ton few (hi, hon!) keyboards with just the profits I made flipping guitars. When one of our younger sons was still in a crib, my wife was complaining to me she couldn't manage to put the mattress down lower and said son was able to climb out of his gayly painted prison. She eventually realized the issue wasn't the construction of the crib, but the guitar cases I had hidden under it (and forgotten about) that were preventing the desired operation from succeeding. This led to a less-than-fun discussion, but I digress.
Across all of those guitars that passed through my hands, not once did I ever think, "boy, this thing sure is heavy!" or "wow, this sounds fantastic for how light it is!" The ones I gelled with (I suppose some might say "bonded with") stuck around. The ones that didn't, well, I flipped them to fund other guitars (and keyboards and fun stuff). There are a few guitars I moved on that I wish I had back (<cough>Tonesucker(tm)</cough>) and a few that I foolishly moved out that I did get back (most famously, a Hamer Studio FM wrap-tail that...well, never mind, long story). At no time, however, did weight alone ever figure in to the calculus.
I am sometimes amused when I read posts--here and elsewhere--of people saying "I absolutely will not consider a guitar that weighs more than <x> pounds!" What if it was the sonic equivalent of the second coming of <insert your own personal messiah here>? You wouldn't at least ponder the possibility? What if it also had a neck to die for? Still no? Fretwork that was sublime? Not worth considering, eh? An oddity in the wiring that allowed you to get exactly *that* tone you hear in your head? Nope, weighs too much, hard pass, I guess.
The way I view it, any particular guitar should be evaluated as the sum total of the parts (or metrics), not on any one factor alone. But, well, that's me. And I'm a little odd. So, there's that.
